2 outfitting choices for retaining heat

Stay Warm1. Lay out a big pile of cash for a thin drysuit. The rubber gaskets at the neck and cuffs exclude all water, leaving you dry inside (as long as the material is breathable). Models with integrated booties instead of ankle gaskets are easier to get on and more comfortable, and a relief zipper for bathroom breaks is a must.

2. Lay out a smaller pile of cash for a three- to five-millimetre layer of neoprene. Farmer John leg/torso models (starting at $85) make a good base layer that won’t impede arm movement. Then add supple neoprene or even polypro, and a spray jacket on top. Just make sure you empty your bladder before suiting up.
